No, I didn't have any traction control issues. It would just bog due to lack of power to the wheels.

 

I did not call you arrogant, I called your grandstanding arrogant. Saying you can easily do something that many before you (with more experience) have tried before. Some have been racing this car for 6-7 years, you made claims after having had yours to the track once. I also said you had good runs, which you did.

Also, must not have looked at the info I posted because if you had read even the beginning, you would know this is not an electronics issue, it is literally a delay valve, totally mechanical. This means you are not putting out the 229tq that the car is able to produce until the entire clutch is engaged, which is delayed by the valve. I did not post this info to make myself sound more knowledgeable, I posted it so others, like yourself, who race, can use the info to try and gain an advantage. Everyone is throwing thousands into their engines, and the thing you need in a manual to really put the power to the ground is being delayed by a $2 part.

I never said anything about 60's, like I stated, I am not a drag racer, but I have been around a track or two. I simply said that if you were able to put the tq to the ground ALL AT ONCE, you might not be complaining about a lack thereof. I brought this up,

I would really like to know what a full bolts XF is, and how far into the 13s you are intending to go, then we can continue our discussion. But if you have no intention of wanting to learn more about the car, like not reading what I posted, that is your choice.

 

Fair enough. I got what you are saying and I didnt click on the link because I am at work. cant get deep into this at work. I would be very happy to get that delay thing off.
my point on the car not having enoughb tq was that it doesnt have enough tq to really cut a good 60's, push that 3000+lbs out of the hole good. when u rev and dump the clutch due to lack of power to the wheels, it kind of falls on its face. My 570lbs of tq cobra (at the engine) would bog on slicks even when launching at 6000RPM. the car weighted a bit more 3800lbs with me in it. So, a crossfire with 229tq will bog each time you dump the clutch. Seriously, u have one, go and try it, If you dump the clutch and if you hook, it will bog, I put money on this.

Other than that, thanks for the advice and I will look into clutch delay thing and hopefully fix it. it should improve my times even better then.

full bolts on in my book is: Full exhaust, intake, custom tune, (and a few other tweaks, pieces to bolt on such as throttle body, intake madifold, etc. it all depends on the kind of car you drive) I guess we can add injectors to it as well.

I have heard people bring their corssfires upto 275-285hp with mods. I mean once again, if your 3000lbs car isnt seeing a 13 second run after with that kind of power, then please dont blame it to the car. I am not here to put anyone down. I am just stating facts and I have always been hated for my unbelievable claims. I have posts to prove them and then other posts to back my claims. I say a nicely modded N/A car can hit a, hmmmmm.... ~13.6@102mph~ on a nice day!

 

Muscle, I did not mean to get into a pissing match, just a couple of guys exchanging ideas, the same way we will when we drink a beer the first time I meet you

I hope a NA XF does hit those numbers, and hopefully it will be you.

Now I only need to talk to some benz specializing tranny shops and see if and how easy it is to modify/replace the CDV, any ideas???

 

No big deal at all, Did somebody say beer? I can't wait!

I really want to get that clutch delay thing taken care of. It should free up a lot of power to the wheels then!

 

I contacted two companies that specialize in CDVs and have gotten no where. It appears with the limited number of mercedes manuals in the states that it will be a little harder to find. BMW CDVs are a dime a dozen at $35 a piece, now if I can only find the benz ones.....

 

Here's a really dumb question......how much of an effect might it have if you just remove the air filters (just during track time of course) ?

Or, why not just take gramma's medical oxygen cylinder & tap that pure O2 stream into the intakes (with a prescription of course) ?

 

I wouldnt do it. It it will suck up every dirt, dust, bug in the air. aboyut the oxygen tank, it will blow up. Too much air and little bit of fuel = lean and too lean = kaboom

 

It actually has a negative effect because the air going into the intake is so turbulent

 

I would think an expert drag racer like yourself would be able to cut a better 60' time than a 2.xx

not bad times, you are within 3 or 4 car lengths behind my hhr with those times. Post up some videos on your next run if you can.

 

thanks!

the car won't do good 60' no matter who you put behind the wheel. As explained before there is a delay valve which doesnt really allow all the torque to go to the wheels upon launch, plus the car already doesnt have much torque so it has a hard time pushing 3000+lbs off the line. with some tuning, i can see it cutting 1.9s but stock, 2.1 to 2.0 is pretty much all she's got.

I have cut 1.7s and 1.8s on street tires multiple times with other cars.

My next run video is exactly the same as the video you have seen at the original post. I can upload them and post them up later tonight.

 

i was just teasing, a 2.1 on stock tires is pretty good. as for the vid, not sure how i missed that lol. i will go check it out, i like watching our cars on the track.

yeah you will get the 1.9x with just a good set of tires on lighter wheels and a cai i bet.

 

With a NA's horsepower, torque, weight, and 3.27 gears, I don't think it's likely any NA cars are goin to brake the 2 sec. 60' barrier.
But with some 3.55 or better yet, 3.73's......now we're talkin.
